| "...and I don't take any advertiser money..." "As usual, this review is not sponsored (nor does any company get to preview anything I review), and I don’t take any advertiser money from any companies I review." How many reviewers are required by the manufacturer to send back the equipment ... | |
| Directional wires/cables @r27y8u92 I like this quote from Ralph Morrison. If we accept the idea that fields carry energy in space, it must be true at all frequencies. That is the law. If it is true for light, it must also be true for 60Hz power and at DC. For utility ... | |
| What is the true impact of power supply differences - Japan, US, Australia? @richardbrand I found this YouTube video on the Net. https://www.youtube.com/watch?v=W0_1xRqT8uU It appears there are three options for Mother Earth Grounding. One as described in my post above. Note the mention of the RCD breaker. That ... | |
| What is the true impact of power supply differences - Japan, US, Australia? @richardbrand Your Utility Power distribution system method used in Australia is different than ours here in the U.S. You use a 3 phase 4 wire power system to feed a housing development as you mentioned in your thread. Here is part of a white ... | |
| Directional wires/cables @mclinnguy Said: 02-12-2025 at 04:29pm I would interpret "immediately" to mean small fractions of a second after flipping the switch, after the energy in the lines has completely been absorbed by the load. I think the answer is instantly. Th... | |
| Directional wires/cables @jea48 The Energy travels from the source >>> to the load (in one direction) Okay, I got a simpler question, what if the load is disconnected before the energy gets there, what happens to that energy? It breaks the circuit. No c... | |
| Directional wires/cables @mclinnguy Said: For my own curiosity wondering how far the "signal" would go: From what I gather this "signal" travels in this medium at a rate of 0.7c, or about 195,000 km per second, so at 60Hz every 0.0167 seconds the energy wave can travel ... | |
| Directional wires/cables @jeffbij said: But @jea48, your last paragraph just made my brain explode. Does that mean if Jimmy Page plays a cord on his guitar in LA that they can't hear it in NYC. LOL You referring to this? I don’t know why cables are directional. I... | |
| Directional wires/cables @mclinnguy I watched the video on cable directionality. The guy thinks the signal travels back and forth in the wire. It doesn’t. If it did then cheap PVC insulation would be all that is needed for the dielectric used to cover the bare wire. ... | |
| Directional wires/cables @rodman99999, Thanks. Were it the DC voltage/current, from an amp's power supply, modulated by the amp's output devices, into an amplified musical signal; it would appear much more complex, but: still a sinusoidal wave. ... | |
| Directional wires/cables I’ve referenced this I don’t know many times over the years. The article is from 1993. Old yes. Wires have been around a lot longer than that. Actual measurements for those that say, "If it can’t be measured then it can’t be true." After measur... | |
| Directional wires/cables Wow, all this technobabble is giving me a splitting headache. I received my EE in 1976. @stereo5 Were you taught the signal travels in the wire or travels in the spaces between the wires? . | |
| Directional wires/cables @rodman99999 Said The ’S’ stands for Sinousoidal electric field, which when combined with it’s magnetic field, results in the Poynting vector that determines the direction and strength of an electromagnetic wave’s energy* flow. *our systems’ AC... | |
| Directional wires/cables I should have posted this in my post above 02-11-2025 at 01:12pm The Late Robert Crump. One example of who he was. TG Audio Lab SLVR Power Inlet Cords (August 2002) . | |
| Directional wires/cables @retiredaudioguy said; However, to the dismay of audiophiles, and the profit margin of cable manufacturers, the velocity of the wave along the wire is dependent of the electrical characteristics of the wire - which are dependent on the physical ... |
